Abstract. This paper lists the problems during the stability analysis of long span CFST arch bridge and the corresponding modeling method. Based on the construction control of an orthotropic long span CFST arch bridge, a FEM model had been established to analysis the stability of its rib during the concrete pumping. The conclusion shows significant importance to the bridge’s construction process.

In recent years, concrete-filled steel tube (CFST) was developed and used extensively in civil engineering in China. In this paper, the method for stability analysis of long-span CFST arch bridge was introduced. Based on Jingyang River Bridge in Hubei province of China and finite element method, the spatial model was set up. Both linear and nonlinear stability of long-span CFST arch bridge in construction process were analyzed. The result indicated the influence of geometrical nonlinearity was small and the influence of material nonlinearity was evident. So, for analyzing the stability of long-span CFST arch bridge, the influence of geometrical nonlinearity and material nonlinearity must be considered at the same time. The results of paper were used to provide the basis for the construction control of the bridge.

In view of huge destructibility of the near-fault ground motions, structures with long natural vibration period are liable to fall into nonlinear reaction stage. Based on a full understanding of the near-fault seismic spectrum characteristics, the out-of-plane seismic response of a long span concrete-filled steel tube (CFST) arch bridge was studied in depth, and the research result could offer a reference for near-fault aseismic design.

Long-span bridges are always a multi-support structural system, and seismic ground motion can vary significantly over distances comparable to the length of such kind of bridges, so it’s difficult to carry out shaking table tests because of the restriction of the dimension and amount of shaking tables. This paper discusses the multiple sub-table cordwood system is used to conduct a study on the seismic testing of a three-span irregular Concrete filled steel tubular (CFST) arch bridge with the objective of investigating the dynamic performance of the bridge under spatial earthquake motions. The development and testing of the bridge model and selected experimental results are discussed then. The seismic response and response characteristics of acceleration, displacement, internal force, and strain of the structure under earthquake excitations are gained, which can provide test data and basis to evaluate the seismic performance of this CFST arch bridge or other similar structural system design.

Monitoring and controlling of vertical construction for main arch ribs is most important for concrete-filled steel tube (CFST) arch bridges due to high risk. Controlling the difference of elevation between the two main arch ribs has direct influence on the mechanical behavior of lateral brace, towers and temporary hinges at arch abutments of main piers. Therefore, transverse synchronization control is the main priority in vertical rotating construction phase. Taking a half-through CFST arch bridge in Shijiazhuang City as an example, this paper make a study of transverse synchronization control of the two main arch ribs during vertical rotation. The finite element method (FEM) software-Midas is employed to simulate the main arch ribs in rotation construction phase, and maximum value of the difference of elevation between the two main arch ribs is obtained to offer reference and basis of vertical rotation construction of this bridge.
